The 2005 Pacific hurricane season was the least active season since the 2001 season, producing 16 tropical depressions; 15 of which became tropical storms or hurricanes. The season officially started on May 15, 2005 in the eastern Pacific, designated as the area east of 140°W, and on June 1, 2005 in the central Pacific, which is between the International Date Line and 140°W, and lasted until November 30, 2005. These dates typically limit the period of each year when most tropical cyclones form in the eastern Pacific basin. This timeline documents all the storm formations, strengthening, weakening, landfalls, extratropical transitions, as well as dissipation. The timeline also includes information which was not operationally released, meaning that information from post-storm reviews by the National Hurricane Center, such as information on a storm that was not operationally warned on, has been included.

The first storm of the season, Hurricane Adrian, formed off the southwest coast of El Salvador and made the closest approach of any hurricane to the country on record. Most of June was quiet until the end of the month, when two tropical storms developed. July remained inactive as well, as only two tropical storms formed. In August, the activity picked up somewhat; the Central Pacific had its first and only depression of the year and four tropical storms, two of which became hurricanes, forming in the Eastern Pacific. September was the most active month of the year; six tropical storms formed, four of which became hurricanes, and two of the hurricanes strengthened further to become the only major hurricanes of the year. The strongest storm of the season was Hurricane Kenneth, whose remnants briefly threatened Hawaii near the end of the month. Activity sharply dropped off in October as only one tropical depression formed. No storms formed in November in both basins, and the season ended on November 30.
